Problems Causing Delays and Risk Factors in Welding Construction Projects of Thailand

Welding delays are one of the major risks in steel construction industry in Thailand. Therefore, it is essential to study and analyze the risk factors that lead to problems causing welding construction delays. This studied focused on delay risk factors in causes of construction projects collected from literature review having the different construction processes, project period, culture, countries, and amount of delay factors for contribution in welding construction projects. Questionnaire surveys and interviews were conducted on major companies connected to welding works in support of the construction projects in Thailand to survey thought problems causing delays and risk factors. Risk factors related to internal and external risk were rated among the risks identified problems. Issues such as material receiving, performance, qualified and language barriers were also highlighted in the questionnaire and during interviews. Notably, the problem such as "multilingual and multicultural" caused ineffective communication. A case study used the FMEA technique to analyze the severity, occurrences and detection, and evaluate to risk priority number. Significant risks were analyzed and compared between the Modified RPN and WRPN method for finding the "Critical risk". The new finding can contribute additional help for project managers to predict and mitigate welding construction project delays.
